Don't take my words 100% but I get the same thing and people are using the virtual torque tables to get rid of it. I believe they are increasing the torque values in these RPM/airmass regions to get rid of it:
You can see from the above log that there is "Torque Management Advance" that is pulling timing. But if you look at the immediate torque source it is "None". I have tried the max torque tables as well and from the screenshot the final throttle torque request is above the maximum engine torque.
The immediate torque control is very low at 413 ft-lbs, but if its source is still set to "none" I don't believe it to be the source of the problem.
Our biggest problem is all these torque PID's that seem to contradict one another and you can't find any information on what they actually mean and how they correlate to the tables we have available.
